The 'L Screen'..

I do like my version better in pretty much every way..except one. His version has the home-screen icons in an L shape, while mine are just along the bottom. He said that on his it was an option to make his that way or not...but for mine I can't find it anywhere in my options.

Any help as to how to make my version have the 'L', or is it even possible? Or is there an app theme to make the new version that way?
